. 3eme-.MACHINE f To all whom imag concern.' l l Beit known'that I, CHARLES `citizen of the United States, residing at Rosedale, in the county of Wyandotte and State of Kansas, have invented certain newf and useful Improvements in BoringlMachines, of which cation. 7

the following a 'speci- My inventionl relates to new andhuseful improvements in wood boring tools, thek ob? ject of my invention being tof provide ara portable boring tool orniachine which ymay be readily employed in restricted spaces, such as in boringv holes through the sills of freight cars or through a series of rafters i where an kordinary bit and brace could not` be employed. i

ing means so arranged in acommon frame that the bit may be driven from a" shaft'eX-- tending at an angle tothe bit. .e

A further 'object of my invention'istoprovide 'a'guide upon which'this yframe'may be mounted to insure the boring'of straight holes. 1

`VpVith these and other objects in` view,` my invention will be more fully described, illus- 'trated in the accompanying drawing, and

then specifically pointed outk in the claims which are attached to. and form apart ofk e and 24 holds the shaft A20 ragainst inward movement and the sleeve 23 against l move.

Fig. 2 is a vertical sectional view ,taken` through thelongitndinal axis of thebit re#` ceiving sleeve of the machine; Fig., 3 is a fragmentary top vplan view, bringingfoutV more clearly ythe manner in which the "bit carrying frame is mounted upon 'the' guide; Fig. 4 is a sectional view on the line of Corresponding and'likeparts are referred to in the following description and indicated in all the views of the drawin'gby the same referencey characters. y

The preferred embodiment of'my invention consists primarily of a ybit carrying frame, indicated as a whole by the numeral 10 anda guide member 11. The bit carrying frame is substantiallyl rectangular in shape,y

being formed from strip metal and in two parts. `The main portion of the frame is bent into U-shaped configuration to provide a top 12and spaced sides 13 andli.
